Yep, I'm a crazy dedicated card maker :3 got still more to upload!
Anyway, why would it be better without stacking in your opinion? After all, it would require a lot of cards to work with weapons (6 weapons, 6 animated and some forges) and can't work with unstealable/indistructible shields, to negate the OPness 5 upped forges and, say, a Jade Shield would be (like 12 immaterial damage reduction, you would have to destroy every single forge).
With only 1 weapon dealing damage, you could choose to build a deck focused on dealing high damage with, say, a momentum'd titan, but every focused deck strategy has its weaknesses.. high weapon damage would mean little space for control/creatures/other stuff, and heavily relying on getting a lot of forges and weapons soon!
